Thanks for the Tony Smith lead. Yes his two 4-dim cosmology with four 4-dim compactifications and an internal spacetime is vastly different from my two spacetime cosmology with 3 6-dim compactifications: [26d-2(4d)=18d=3*6d]; and an external (to our universe) spacetime. But apparently he was the first to realize the need for two spacetimes.

My post on the PhysicsForum, called Stringy Spacetimes, did not generate a single reply. And the entire cosmology posed as a series of questions, Questions of String Cosmology, generated only one....which said that he also thought inflation was caused by or at least coincident with compactification, but the the rest was speculative and at best prescient, which means to know before hand.

So I have some hope that I said something meaningful, hopefully very meaningful, of cosmic proportions. Thanks for your contributions.
